A facility used to house computer systems and associated components, such as telecommunications and storage systems. It generally includes redundant or backup power supplies, redundant data communications connections, environmental controls (e.g., air conditioning, fire suppression) and various security devices. Large data centers are industrial scale operations using as much electricity as a small town.
WAN Optimization, Also known as WAN acceleration, is the category of technologies and techniques used to maximize the efficiency of data flow across a wide area network (WAN). In an enterprise WAN, the goal of optimization is to increase the speed of access to critical applications and information.

An application delivery network (ADN) is a suite of technologies that, when deployed together, provide application availability, security, visibility, and acceleration. Gartner defines application delivery networking as the combination of WAN optimization controllers (WOCs) and application delivery controllers (ADCs).

Server & Storage
A server is a computer program or a device that provides functionality for other programs or devices, called "clients". This architecture is called the client–server model, and a single overall computation is distributed across multiple processes or devices. Servers can provide various functionalities, often called "services", such as sharing data or resources among multiple clients, or performing computation for a client. A single server can serve multiple clients, and a single client can use multiple servers. A client process may run on the same device or may connect over a network to a server on a different device.
A storage is frequently used to describe the devices and data connected to the computer through input/output (I/O) operations that is, hard disk and tape systems and other forms of storage that don't include computer memory and other in-computer storage. For the enterprise, the options for this kind of storage are of a much greater variety and expense than those related to memory.
Software as a Service
Software as a service (SaaS) is a software distribution model in which a third-party provider hosts applications and makes them available to customers over the Internet. SaaS is one of three main categories of cloud computing, alongside infrastructure as a service (IaaS) and platform as a service (PaaS).
Cloud computing is a general term for the delivery of hosted services over the internet. Cloud computing enables companies to consume a compute resource, such as a virtual machine (VMs), storage or an application, as a utility (just like electricity) rather than having to build and maintain computing infrastructures in house.

Backup & Recovery
Backup refers to the copying of physical or virtual files or databases to a secondary site for preservation in case of equipment failure or other catastrophe. The process of backing up data is pivotal to a successful disaster recovery (DR) plan.
Recovery is the process of restoring data that has been lost, accidentally deleted, corrupted or made inaccessible for any reason. In enterprise information technology (IT), data recovery typically refers to the restoration of data to a desktop, laptop, server, or external storage system from a backup.

CCTV & Video Management
A CCTV (closed-circuit television) is a TV system in which signals are not publicly distributed but are monitored, primarily for surveillance and security purposes.
A video management, also known as video management software or a video management server, is a component of a security camera system that in general: Collects video from cameras and other sources. Records / stores that video to a storage device.

Outsourcing service is the use of external service providers to effectively deliver IT-enabled business process, application service and infrastructure solutions for business outcomes. Outsourcing service, which also includes utility services, software as a service and cloud-enabled outsourcing, helps clients to develop the right sourcing strategies and vision, select the right IT service providers, structure the best possible contracts, and govern deals for sustainable win-win relationships with external providers. Outsourcing service can enable enterprises to reduce costs, accelerate time to market, and take advantage of external expertise, assets and/or intellectual property.
